CHARLES H. WILLIAMS, OF SYRACUSE, NEW YORK.

IMPROVEMENT IN DISH-"WASHING MACHINES.

Specification forming part of Letters Patent No. 143,484, dated October7, 1873; application filed October 22, 1872.

To all whom it may concern.-

Be it known that I, CHARLES H. humans, of the city of Syracuse, NewYork, have invented a new and useful Improvement in Machines for WashingDishes; and I do hereby declare that the following is a full and exactdescription of the said invention.

Figure l is a transverse section on line 3 y of Fig. 2. Fig. 2 is alongitudinal vertical section of the dish-washer.

My invention consists of a semi-cylindrical box of sheet metal or othersuitable material, suspended upon bearings at either end, and incasedwithin a complete cylindrical box provided with buckets, of a peculiarform, to lift and throw or splash, and also perforations in its ends toallow the water to flow in from a tub which incases the whole mechanismto be used in washing or cleansing dishes.

To enable others to manufacture and use the machine, I proceed todescribe its construction and operation.

The complete cylinder has extending from its ends, in a line with itsaxis, hollow journals, which rest in suitable bearings formed in theends of the tub or case of the machine. To one of these journals isattached a crank or other suitable mechanical device, to which the poweris to be applied to revolve the said cylinder. The buckets, which arecomposed of sheet metal, are V-shaped in their sections, and extendinward from the inside of the cylinder. They are perforated to morethoroughly agitate the water as it is lifted over the semicylindricalvessel containing the dishes to be cleansed. The semi-cylinder hasjournals extending from its ends, which find their bearings in thehollow journals of the complete cylinder. The dishes are secured bythree or more corrugated straps fixed in the bottom and sides of thesemi-cylinder.

The dishes are intended to be kept stationary in their cradle by theirown gravity, while the complete cylinder is caused to revolve aboutthem, to lift the water which flows in from the tub through openings todrench and cleanse the same. The water which falls into thesemi-cylindrical cradle is allowed to pass out and mingle with the lessturbid water in the cylinder and tub, to be again thrown over the dishesimtil they are deemed sufficiently clean.

I am aware that machines have been invented and are now in use forcleansing dishes by throwing water over them by buckets framed in arevolving cylinder while they remain stationary; but they differmaterially from my invention, for which I claim several advantages.

The cradle in my device is not a frame composed of wire, but a completecylinder, which is easy of construction, and which will deflect thewater onto the dishes to more thoroughly cleanse them. The case whichcontains the buckets in my device is formed of a complete cylinder, whenclosed, and prevents the violent splashing of the water against thecover of the tub, and thence through the joints into the room. Thebuckets, which present V-sections, are perforated to break and showerthe water down against the dishes to be washed.

A is the semi-cylindrical cradle, with journals a a resting in thehollow journals 1) b of the complete cylinder or case B. c a c are theV-shaped buckets, which extend inward from the concave surface of thecylinder. 61 d d are openings formed in the cylinder or case, to allowthe water from the covered tub O to flow in. D is the cover of the tub,which is provided with a latch or fastening, and a handle, to make itmore portable. The cylinder B has a segment of itself out off and hungwithhinges, and is provided with a fastening to prevent its being thrownopen while being revolved in the operation of cleansing the dishes. Thecorrugated straps e e 6 hold the dishes in their proper places duringthe process of washing. f f are openings in the bottom of cradle A. Thecock E is used to draw off the dirty water from the tub.

I claim- 1. The sheet-metal cradle A, with its corrugated supports 0 e candopenings f f f, supported by journals a, which rest in hollow journalI), all arranged as described, for the purpose set forth.

2. The revolving cylinder 13, having V- shaped perforated buckets c, incombination with the cradle A, the whole being supported by hollowjournals 1) b, bearing in the ends of the closed tub 0, all arranged asand for the purpose set forth.
